Abstract：Chinese think tanks are thriving and facing a rat race. The think tank influence concerns the core competitiveness and the outcome of the think tank work, and is a cornerstone of the sustainable development of the think tanks. Based on the information-solution chain, combined with the knowledge utilization theory, the elite theory and the communication theory, this paper presents a five-stage mechanism of the generation and propagation of the think tank influence. Starting from the constitutive elements of the influence, the literature/network investigations and case studies, this paper reviews the think tank development and makes relevant suggestions. Think tanks are supposed to enhance their influence, to improve their strength and ability, to listen to the public demand and to provide their products and services systematically.
